The Flower Filament by designer Ha-Na Yeom combines nature with technology. The Flower Filament lights up only if there is a flower in it but the flower also acts as the switch to light up the hollowed out, light-bulb like design. I'm kinda slow right now so it took me a while to comprehend the concept behind this gadget but as it turns out, it is pretty simple. And so is this cute design. Cheers.
